FLlER-FRAME.

SPECIFICATION forming part of Letters Patent No. 376,118, dated January 10, 1888.

Application filed August 26, 1887. Serial No. 247,927. (No model.)

To all whom it may concern.-

Be it known that I, HERMAN F. STRAW, of Manchester, county of Hillsborough, and State of New Hampshire, have invented an Improvement in Flier-Frames, of which the following description, in connection with the accompanying drawings, is a specification,

. like letters onthe drawings representing like parts.

This invention is an improvement on that class of frame employing a flier such as shown in United States Patent No. 317,323, wherein a latch holds the upper end of the quill on which the bobbin is reciprocated.

In the practical use of the flier shown and described in the said patent the latch is liable to become disengaged from the upper end of the quill; and to prevent this, which is the chief objectof my invention, I have combined with the latch a locking bar or device under the control of, preferably, the shipping mechamsm, whereby the latch is held firmly and positively in place, while the driving-belt runs on the fast pulley; but I may, if desired, disconnect the locking-bar from the shipper-lever and work the said bar by hand without moving the shipper-lever.

Figure 1, in front elevation, shows a snfficient part of a flier-frame to enable my invention to be understood; Fig. 2, a right-hand elevation of the machine shown in Fig. 1, and Figs. 3 to 5 show details to be described.

The flier A, quill O, spool or bobbin D, and latch b are all substantially as in United States Patent No. 317,323, wherein like letters are used to designate like parts.

The frame-work A of the machine has a suitable guide, A, for the belt-shipper A, it having a loop, as shown in Fig. 1, for the reception of the belt A which may thus be placed on either the loose pulley A or the fast pulley A but partially shown on the usual driving-shaft of the frame.

stopping the machine.

The shipper-lever B has jointed to it a link, H, which in turn is attached to an auxiliary lever, H, having its fulcrum at H the upper end of the said lever H being loosely engaged with a long locking-bar, N, which in practice is extended past all the fliers, the said bar being, as shown, made to enter a groove in the usual bearing, N, for the nose of the flier,the said bar being also preferably guided by means of bolts N extended through slots therein.

The locking bar, as herein shown, has a stop, 92, provided with a registering-hole, a, which is placed in line with a pin or projection, a, on the latch b, so that the said pin may enter the said hole whenever the belt is on the loose pulley, as in the drawings; but when the belt is on the fast pulley and the machine is running the stop a, by the movement of the bar N to the left, is placed in position to stop or arrest the upward movement of the pin or projection nflthus preventing the lifting of the latch and the release of the quill.

I may disconnect the link H from the lever B and remove the auxiliary lever, and then the bar N can be moved only by the operator and by direct application of the hand thereto.

The dotted lines at left of Fig. 4 show the quill turned out in position to permit the bobbin to be dofifed.

I claim 1. The quill, the flier, and the latch provided with a pin or projection, combined with a locking bar or stop to co-operate with the said pin or projection (and prevent or permit, as desired, the lifting of the latch, substantially as described.

2. The quill, the flier, and the latch provided with the pin or projection, and the locking bar or stop, combined with the belt shifting rod and intermediate connections, whereby the bar or stop prevents the lifting of the latch, except when the belt is on'the loose pulley, to effect the stopping of the machine, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
